Background
Most of the currently common ultrasonic endoscopic and intravascular ultrasonic imaging devices are in a single excitation mode in an excitation mode of a transducer, and the transducer is basically excited by high-frequency or ultrahigh-frequency pulses to detect tissues or blood vessels. Since the higher the ultrasound frequency, the faster the attenuation and the shallower the imaging depth, these devices can only detect surface and superficial information, and cannot display deeper tissue and other structural information. For some operations requiring high resolution of superficial images and viewing information of peripheral deep tissues, the operation cannot be satisfied. To meet the above requirements, it is common to use a high frequency transducer or a low frequency transducer combination, the high frequency transducer being followed by a transceiver system, and the low frequency transducer being followed by a transceiver system. However, this method makes the probe part become larger in volume (two transducers are needed), and for some ultrasound devices requiring small probe volume, such as ultrasound bronchoscope (EBUS), intravascular ultrasound (IVUS), etc., the size and volume of the probe are very strict, and the above-mentioned method and scheme are not a good choice for these devices; the other two sets of transmitting and receiving systems also increase the size of a hardware system and the cost.
